Xestospongin C
Product Specifications
UNSPSC Description
Xestospongin C ((-)-Xestospongin C) is a selective, reversible inositol 1,4,5-trisphosphate receptor (IP3R) inhibitor. Xestospongin C acts as an inhibitor of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) pump of internal stores. Xestospongin C blocks IP3-induced Ca2+ release from cerebellar microsomes with an IC50 of 358 nM. Xestospongin C is a valuable tool for investigating the structure and function of IP3Rs and Ca2+ signaling in neuronal and nonneuronal cells[1][2][3].
